IMPROVEMENT IN LIQUID-FUEL BURNERS.

l Specification forming part of Letters Patent No. I169,37 2, dated November 2, 1875 application filed July 27, 1874.

Be it known that I, GEORGE H. PERKINS, of Philadelphia, Pennsylvania, have invented an Improvement in Liquid-Fuel Burners, and in appliances therefor, of which the following is a specification:

The object of my invention is to apply benzine or light spirits of petroleum as a safe and economical fuel for heating, soldering, and other'furnaces; and I attain this object, first, by the use of a burner consisting of a single jointless tube, A, bent abruptly at two points, plugged at the end, and having an outlet-aperture adjacent to the said plugged end 5 and, second, by combining the burner supply-pipe and its regulating-cock q with a vessel, H, through which the said pipe extends, and to which it is soldered at opposite sides of the cock, all as fully described hereafter, and as i-llustrated by the enlarged sectional view, Fig. l, and exterior view, Fig. 2, of the aocompanying drawing.

The jointless tube A, of which the burner is composed preferably a gas-pipe of small diameter-is bent abruptly at x, whence it is continued vertically downward, and is again bent abruptly at y, from which point the pipe extends horizontally outward to a short distance, its extreme end being plugged and welded, and an orilice, m, being made in the upper side Vof the pipe at a point adjacent to the said plugged end, through which orifice the ignited vapor of benzine escapes in the condition of a flame of intense heat. The reservoir from which the burner is supplied is elevated about five feet above the orilice m, and the flame from the burner is prevented from gaining access tothe said reservoir by wire-gauze h, rolled up to a suitable form and packed within the pipe adjacent to the upper bend x, as

shown in the drawing. The object of bending the pipe abruptly at the two points w and y in the manner shown and described is to subject the liquid in the vertical portion K of the said pipe to the heat of the dame, so that it may be vaporized before escaping, and this without preventing access to the orifice m; which is apt to become clogged, and has to beii frequently reamed or picked out with a sharpi pointed instrument. It is essential to the production of a clear and steady flame that the orifice m shall be as close as possible to the plugged end of the pipe.

OAsE Q.

As the jointless pipe itself constitutes theburner, it will be evident that the latter will resist the effects of intense heat much better than ordinary burners of sheet metal, and that it will be especially available, therefore, for the burning of liquid fuel in the furnaces of steam-boilers, soldering-iron heaters, &c.

The ow of benzine to the burner is regulated by a cock, q, on the latter, or more properly on the supply-pipe of the said burner. However carefully these regulating-cocks may .be made they are apt to leak, owing to the penetrating and subtle character of the uid,

which will either drop directly from the cock or else flow along the supply-pipe and burners, and in case of its accidental ignition endanger the building in which the apparatus is contained. I entirely avoid this danger by arranging the cock within a vessel, H, through which the supply-pipe passes and to which it is soldered at the points c c, at opposite sides of the cock, the said vessel not only catching the drippings, but effectually preventing the fluid from spreading along the pipe. The said vessel may, if desired, be provided with a lid.

It is common in vapor-burners to attach to the pipes communicating with reservoirs metallic projections for the dames to play upon, and thus vaporize the fluid. This I do not claim, nor do I claim, broadly, vaporizing the fluid by heat derived from the burner;

but-

I claiml. The within-described burner, consisting of a jointless tube, A, plugged and welded at the end, having an outlet-aperture, m, near said plugged end, and bent at two points, wy, so that the dame at the aperture will act on the bent portion of said endless tube, all as set forth.

2. The combination of the burner supplypipe, its regulating-cock q, and the vessel H, through which the said pipe extends, and to which it is soldered at opposite sides ofthe cock, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
